Platform Level Services

15. My Application Challenge

16. Build a micro service based web application that…..
Scales per request
Requires no deployment effort
Fault Tolerant
Has a RESTful API interface with a Web client

17. The Catch
NO Servers
NO Monolithic App or Explicit Web Service
NO Explicit code for scaling and fault tolerance
And do it within 45 minutes…

18. What Services Could we use?

19. Static Assets in Amazon S3
Internet scale HTTP/S based object store
Inerently Highly Available and Fault Tolerant
Designed for 11 9’s of Durability
Can host static websites
Holds trillions of objects

20. Serverless micro services with AWS Lambda
Event Driven Computing service
Never pay for idle
Scales per request
Supports Node.js, python and Java (or other JVM based languages)
Event triggers from other AWS Services
23 different ‘Power Levels’ of AWS Lambda

21. A RESTful API with Amazon API Gateway
Host multiple versions and stages of your API
Create and distribute API Keys to your developers
Throttle and Monitor API Calls
Cache Responses
Transform Data
Generate SDK’s (Including Swagger Support)
Interact directly with AWS Lambda

22. A NoSQL Data Store with Amazon DynamoDB
Managed noSQL Data Store
Can be either a Document or Key/Value store
Simply provision read and write throughput
Enables you to focuss on your data
DynamoDB streams enables you to take actions on events
Inherently Highly Available and Fault Tolerant

23. Putting it all together

24. The Service Itself
Static Site in S3
www.servicecheck.com
Web Client API Gateway
/serviceCheck
Lambda
serviceLogger

Subtitle
Lorem Ipsum is simply dummy text of the printing and typesetting industry.
Lorem Ipsum has a the industry's standard dummy text ever since the 1500s,
when an unknown printer took a galley of type and scrambled it to make a
type specimen book. It has survived not only five centuries, but also the leap
into electronic typesetting, remaining essentially unchanged.
Here is an example:
- Bullet Point one
- Bullet Point one
- Bullet Point one
It was popularised in the 1960s with the release of Letraset sheets containing
Lorem Ipsum passages, and more recently with desktop publishing software
like Aldus PageMaker including versions of Lorem Ipsum.

it looked like David sort of didn't want to be there. He
was shifting around on his chair like a man who'd just
nicked a Mars bar.”

70. Summary and Next Steps

71. Summary
Utilise Platform Level Services that have built in HA
Use a microservice approach
Use a common interface for services such as RESTful APIs
Store static files in Amazon S3
Use AWS Lambda as the glue between AWS services

72. Next Steps
Sign up for an AWS Account
Try out a new server-less service
Make use of AWS Forums and Support
Come and meet an architect at the loft
